When an ioctl command SW_XXXX is issued, scioctl() checks if the font appropriate for the specified mode is already loaded. The check was correctly done for 8 line and 16 line fonts, but not for 14 line font. The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but were sometimes treated as bit flags. They are now defined as bit flags. 2) screen blinking (two fixes) Removed a redundant call to timeout() in do_bell(). Don't let blink_screen() write to the video buffer if the screen is in the graphics (UNKNOWN) mode. 3) screen saver timeout The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The value of zero will disable the screen saver. If the screen saver is currently running it should be stopped. 4) border color and destructive cursor (two fixes) The border color and the cursor type can be changed via escape sequences. But only VGA can change the border color and set the cursor type to destructive (CHAR_CURSOR) in the current syscons. scan_esc() failed to check this. Reviewed by: sos
